Concentration of metals in locally grown and organic vegetables

By: Stephani Lane & Aaron Pyle

purpose
Purpose
  • To determine metal concentration differences between organic and locally grown vegetables for healthy dietary decisions.
overview our experiment
Overview Our Experiment
  • Researched vegetables and metals to test
  • Determined expected amount of each metal
  • Purchased vegetables from a local store
  • Blended vegetables
  • Made 10, 20, 30, 40 and 50 ppm standards
  • Ran experiment on the ICP
metals
Metals
  • Calcium
  • Lead
  • Magnesium
  • Manganese
  • Sodium
metal benefits
Metal Benefits
  • Ca- Strong bones, dental care, prevents colon cancer, reduces obesity
  • Pb- none
  • Mg- prevent cardio vascular disease, regulates blood pressure, muscle and nerve function
  • Mn- forming bones and enzymes, helps absorb vitamins, healthy function of the brain
  • Na- maintains fluid balance maintains healthy heart, eliminates excess CO2
metal detriments
Metal Detriments
  • Ca- heighten blood pressure, risk of cardio vascular disease, kidney stones
  • Pb- Headaches, joint pain, fatigue, miscarriages
  • Mg- Nausea, low blood pressure, irregular heart beat
  • Mn- Chronic liver disease, psychosis, shaking
  • Na- high blood pressure, kidney disease, osteoporosis
method
Method
  • Weighed out approximately 34 g
  • Blended each sample with 50 mL of water (100 mL for Broccoli)
  • Filtered samples through a Buchner funnel
  • Ran standards
  • Ran samples

Results
  • Magnesium
conclusions
Conclusions
  • Mn found only in organic beets
  • Broccoli had lower organic concentrations, except for lead
  • Beets had higher organic concentrations, except for lead
  • Organic zucchini and potato's were higher in all categories
conclusion
Conclusion
  • Based on our data, a healthier dietary decision can be made based on metal content.
